Multiple pages on the Internet, including answers to this SO question and this page from a training company, say that you should handle Ctrl-C in python with code similar to:

import signal
import sys
import time

try:
  while True:
    print('Running...')
    time.sleep(10)
except KeyboardInterrupt:
  print('Ctrl-C pressed!')
  sys.exit(0)

However, there is a fairly significant problem if you use code with this sort of solution from a Bash loop, like this:

while true; do
  ./python_script.py
done

The issue is that because Python is absorbing the Ctrl-C, Bash doesn't know the script exitted abnormally, so just carries on around the loop and it becomes very difficult to exit.

I asked AI, and it suggested first to give a specific error code to the sys.exit call, which didn't work, then to use the raise call, which did stop the script in a way that caused Bash to exit the loop, but also still gives the Python stack trace.

When asked for a better solution, all the AI could come up with was to add import os, and then use the very un-Pythonic looking:

signal.signal(signal.SIGINT, signal.SIG_DFL)
os.kill(os.getpid(), signal.SIGINT)

Is there really no elegant way to do this properly from Python?
